Tipping Bucket Rain Gauge Rainfall Sensor Measurement Tool with RS485 Pulse Signal Output and 4.5 to 30V Power Supply for Meteorological and Hydrological Monitoring Stations

Item Type: Rainfall SensorMaterial: Magnetic steelRain Bearing Diameter: Approx. 200mm / 7.87inOf Sharpness Cutting : 40°-45°Resolution: 0.2mmMeasurement Error: ±3%Rain Strength Range: 0mm～4mm/min (maximum allowable rain strength 8mm/min)Communication Method: 485 Communication (standard protocol)Maximum Power Consumption: 0.24WWorking Environment: Ambient Temperature: 0-50℃Relative humidity: Power supply range: 4.5~30VPackage List：1 x Rain Sensor1 x Accessory (Random)3 x Screw3 x Wall PlugNote:1. The instrument has been outdoors for a long time, and the operating environment is very harsh. Therefore, always use a soft cloth to wipe the inner wall of the rain of the instrument to keep the rain clean.2. If there are foreign objects such as leaves in the rain outlet, it should be cleaned up in time to keep the waterway unblocked.3. When the instrument is not used for a long time, cover the ring mouth of the instrument to protect the rain .4. It is recommended to clean the instrument once a month for long term work, and once every three months.

• Dual Signal Output: This instrument converts rainfall data into pulse or RS485 signals for direct reading without secondary calculations, operating on a 4.5 to 30V DC power supply.
• Integrated Structural Design: The assembly consists of a one piece shell, filter, funnel, wiring terminal, outrigger bracket, and a rain gauge base equipped with a horizontal bubble for precise leveling.
• Three Dimensional Tipping Bucket: The three dimensional streamlined tipping bucket features a drooping curved deflector tip and an integrated positioning bushing for consistent performance and self cleaning.
• Factory Calibrated Sensitivity: Magnetic steel and reed switches are pre adjusted to specific coupling distances at the factory to maintain a fixed proportional relationship between bucket tips and output signals.
• Meteorological and Hydrological Monitoring: This sensor is suitable for field observation stations, , forestry, and reservoir management to measure precipitation intensity, duration, and volume.
